Has anyone had success compiling on AMD 6176 SE (Opteron Magny-Cours) 2.3 GHz, 4x12 cores. I can get vasp to compile but it segfaults in a number of basic situations.

I have it running OK on an AMD 6174, 2x12 core system. I initially had two sources of segfaults:

When using the PGI compiler I had to compile broyden.f90 with a lower optimisation. I did this by adding the following to my Makefile:

broyden.o:?broyden.F
?????????????$(CPP)
?????????????$(F77)?-O1?-Mfree?-c?$*$(SUFFIX)

When using GCC and linking against my system's pre-compiled ATLAS/OpenMPI libraries I had to remove the -ff2c option from the compiler flags.
